Office365 Exchange Online Plan 2 Sent Items showing only from 20/08/21

[Pwoodlock]

Hi guys, I hope you're all keeping well and getting ready for the Christmas festivities.

I can't seem to track down an issue I am having with a client. I upgraded them to Office365 Exchange Online Plan 2 on the 12th of December and now when we go into their (sent Items) folder we can see the emails sent from Monday which is the day we upgraded to Plan 2, but all the rest of the emails are only showing from 20/08/21 and backwards in the sent items folder. Anything from then on wards is missing.

I checked their outlook online on portal.office.com and it reflects exactly the same as the outlook client. It's not a shared Email etc..
Just wondering if any of you guys have came across this issue before? We really need to find these emails, or even find out why this has happened.

regards

Patrick

Open the older profiles, the sent items are sometimes not in the exports. You have to get them manually.

Usually I just open the PST that I exported in the new profile and copy the sent items over to the new Exchange account.

Hi CallthatGirl, Thanks for your reply

Mmmm..... All we did was upgrade the licence to Plan 2 in the tenant. I didn't think we needed to do anything with a PST file. I will look into it now and get back to you.

Weird, well, look in the deleted items. That's the default for missing emails. I find lost data there all the time.

 

[callthatgirl]

And maybe it went into the online archive, did you set that up for the client?

 

[Pwoodlock]

I looked in the deleted items folder and they're not there either. As in regards the "online archive" I also checked in there too. It's really weird. I am going to rebuild the profile to another profile and see if they pop up in there.

If the owa also shows as missing then a rebuild of a profile is not likely to work. Open a ticket with M$. You have a damaged index on the server side. Can you search for a known sent email? Trace said email from the exchange admin center?

 

[Pwoodlock]

Thanks everyone for the help so far regarding the issue. I am going to open a ticket with Microsoft and also try that rebuild profile just to see.

This is an odd one, we do a lot of upgrades of users mailboxes to increase mailbox capacity...so lots of M365 Biz Std and Biz Premium getting the ExchP2 add-on. Mailboxes just ....increase in capacity with this, nothing should move or get lost in the process.

Just adding the Exchange P2 license to a user isn't enough though....you have to go to users, the "licenses and apps" tab, check the box for P2...and..importantly....expand the little arrow for "apps"...Check P2, and UNcheck P1.

Exactly. Which is why I think something is broken on the server side.

Sorry I forgot to add that in my original post. That's exactly what we have done after with upgraded the licence for the client.

@Pwoodlock any fixes? I got a ticket today with this same issue.

My apologies in the delay in getting back to you! I hope you had a great Christmas and New year.

At the moment we are still sorting out the issue with Microsoft. We actually found the Email from the Compliance portal ==> Content Search so we exported an xlsx list and are waiting for MS to get back to us as to why their not showing in the Browser or Outlook Client.

Hopefully this will help someone out in the coming future also. I will keep this thread updated as the issue progresses.

The last thing we were instructed to do is to use the Compliance Portal with Search Index via a Global Admin and conduct a search via there.

Create and run a Content search in the Microsoft Purview compliance portal - Microsoft Purview (compliance) | Microsoft Learn

We found the emails via the search in the portal etc... But now have reported back to MS of how to get the emails back in to our clients Online Email Portal which in turn will hopefully show back up on the desktop client too!

Maybe those were tagged somehow and automatically went to in-place archive? https://lazyadmin.nl/office-365/outlook-online-archive-for-office-365-explained/

No unfortunately they weren't. We checked. Well at least they're there in the compliance portal search. We just need to get MS to get them about to our client, and if not, we will down download the pst file and import it to that account, but we want to know why this happened in the first place !!
